I am about to look through my stash of Norton bits to find a set of triple trees for a friend's 650 SS.
I think I have a mix or featherbed and early Commando triple trees.
Are they interchangeable, and if not how do I identify the differences?

The thread on the stem is slightly different, Domi vs Commando. 26tpi vs 28tpi.

Thanks elefantrider. Does that mean if I have a matched pair, top and bottom, an Atlas and early Commando set is interchangeable?

yes, as far as I know. Though the internal headstock spacer may not be same length.
